Why Operation Chariot stands out among wartime commando raids

What was the most outrageous commando raid of the Second World War?

Operation Chariot at Saint-Nazaire, where HMS Campbeltown was sacrificed as an explosive charge against the strategically vital Normandie Dock.

The panel selects Operation Chariot as the most outrageous commando raid while also noting extreme SAS, SBS, and Long Range Desert Group operations. HMS Campbeltown, a former American four-stack destroyer, was driven into the Normandie Dock gates at Saint-Nazaire with concealed explosives aboard. Destroying the only Atlantic dry dock capable of servicing a German capital ship justified an operation that sounds almost implausible in outline. The answer also distinguishes Campbeltown's destroyers-for-bases transfer from Lend-Lease.
